Ultra-high capacity

These second generation 18650 cells offer world-highest capacity at 3400mAh.

Only 68mm in height

We are the first to offer protected 3400mAh 18650 li-ion with only 68mm in height. That makes it highly compatible with all 18650 flashlights and chargers in the market.

Button top design

The protruded button top design makes it work with any flashlight that uses hardware anti-reversed battery polarity protection. It also ensure good conductivity when multiple batteries are used in series.
